Description:
R838 rutile is a generic titanium dioxide prepared by the sulfuric acid method that is a non-toxic, chemically stable white powder treated with a silicon-aluminum coating and special organic solvents. After air-drying late in the production process, R838 has excellent dispersibility and a strong whiteness, brightness, glossiness, and good hiding power, achromatic power, as well as excellent weather-resistance and non-chalkiness.
Characteristics:
R838 is a rutile titanium dioxide pigment treated with an inorganic silicon-aluminum coating and organic solvents; which has an excellent optical brightness, whiteness, glossiness, tint-reducing power, as well as weather-resistance and dispersibility.
Applications:
Water-based coatings, emulsion paint, powder coatings, printing ink, other areas
Packaging:
25 kg paper-plastic bag; large 500 kg or 1,000 kg bag
